The yellow -galaxy bolt is especially for attaching handrails in concrete or stone walls. The metal plug has a conical bolt with metal parts around it. By turning the handrail holder on the threaded end of the bolt, the metal parts are pushed apart. For example, the Keilbout clamps stuck in the hole. Always ensure a sufficient deep hole (approximately 10 mm deeper than the plug long). Diameter borehole: M8 Ø 14 mm
